BOILER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/155005
Kind Code:
A1
Abstract:
Provided is a boiler system wherein the heat release loss in a boiler having a feed-water preheater can be reduced, and the boiler efficiency can be improved. A boiler (20) has a boiler main body (21) for burning; a discharge portion (25) for discharging combustion gas (G4) generated by the boiler main body (21); a discharge path (24) which communicates with the boiler main body (21) and the discharge portion (25), to allow combustion gas (G1 to G4) to circulate therethrough, said discharge path (24) having a circulation portion (24D) extending vertically; a feed-water preheater (40) which has a heat exchange portion (44) being disposed in the circulation portion (24D) and having feed-water (W1) to be supplied to the boiler main body (21) circulated therethrough, and which supplies feed-water (W3) to the boiler main body (21) after preheating the feed-water (W1) at the heat exchange portion (44) by the combustion gas (G2) passing through the circulation portion (24D); and a feed-water temperature measurement means (50) for measuring the feed-water temperature, i.e., the temperature of the feed-water (W1) circulating in the heat exchange portion (44). A combustion control means controls the combustion in respective boilers (20) on the basis of the feed-water temperature measured by the feed-water temperature measurement means (50).
